of heaters. Studying the instructions first may save you
considerable time and money later. Observe the following
procedures, and cut your installation time to a minimum.
5.
6.
TO REDUCE RISK OF FIRE OR ELECTRIC SHOCK:
1.
2.
3.
4.
Disconnect all power coming to heater at main service panel
before wiring or servicing.
All wiring must be in accordance with the National and Local
Electrical Codes and the heater must be grounded.
Verify the power supply voltage coming to heater matches the
ratings printed on the heater nameplate before energizing.
This heater is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces.
7.
8.
9.
Do not insert or allow foreign objects to enter any ventilation
or exhaust opening as this may cause an electric shock,
fire,or damage to the heater.
Do not block air intakes or exhaust in any manner. Keep
combustible materials, such as crates, drapes, etc., away
from heater. Do not install behind doors, furniture, towels,
or boxes.
A heater has hot and arcing or sparking parts inside. Do not
use it in areas where gasoline, paint, or flammable liquids are
stored.
Use this heater only as described in this manual. Any other
use not recommended by the manufacturer may cause fire,
electric shock, or injury to persons.
This heater is not approved for use in corrosive atmospheres
such as marine, green house, or chemical storage areas.
SAVE THESE INSTRUCTIONS
CAUTION
!
Installation of Recessed Back Box
in Existing Construction
!
1. Provide a wall opening 14-1/2" (362mm) wide by 18-1/2" (470mm) high
at the desired mounting height, but no closer than 8" (203mm) from floor.
(See Figure 2.)
FOR SAFE OPERATION AND REDUCED RISK OF FIRE, INJURY OR
HEATER DAMAGE, OBSERVE THE FOLLOWING:
1. Do NOT use a remote thermostat with this heater. Built in thermostat
cycles the heating element only. Fan delay control automatically turns
fan ON and OFF, and provides a fan delay OFF feature to remove
residual heat after thermostat has turned heating elements off. Wiring
of heater in any manner which defeats the fan delay OFF feature can
result in overheating and permanent damage to heater, and will void
the warranty.
2. For wall mounting only with air discharge downward. Do NOT install
in floor, ceiling, upside down (air discharge upward), or sideways.
3. Do NOT operate heater without grille installed.
4. Maintain the following clearances:
• Bottom of heater to floor – 8” (203mm)
• Sides of heater to adjacent wall – 8” (203mm)
• Top of heater to ceiling – 36” (915mm)
5. This heater is hot when in use. Do NOT install heater behind door,
behind towel rack, inside closet, where drapery could touch heater or
be damaged by heat, or where airflow to heater may be obstructed.
Keep electrical cords, bedding, furniture, and other items away from
heater.
6. Heater must be cleaned periodically (at least annually) to assure
proper performance and prevent overheating. See section on
cleaning and maintenance.
Note: Locate so at least one side of opening is at wall stud.

Note to Installer: Converting heater to half wattage
(Not applicable to WH3150 and WH3180, 120 Volt Models)
The WH Series wall heaters are manufactured and shipped at the higher
rated wattage. Full wattage heaters can be converted to half wattage by
doing the following steps.
1. Remove the red jumper wire as shown in Figure 3 and discard.
2. To permanently make the heater half wattage, cut the male terminal
spade, carefully not to damage the cold pin and discard.
3. Mark the wattage of the heater on the white label inside the backbox.
Male terminal spade
Installation of Heater Assembly and Grille
After back box is completely installed and no further construction dirt is expected, clean debris from back box and remove heater assembly from its carton.
Then refer to Figure 5 and proceed as follows:
1. Insert the heater assembly into back box, placing the four mounting holes
(with key-hole slots) over the screws in the box. Tighten all screws securely.
2. If surface-mounting frame is used, ensure that the frame is even with all four
heater assembly tabs before tightening screws.
3. Connect the two disconnected switch wires to the heat control switch (thermostat) leads using wirenuts. After connection, push wires back into the
opening.
4. Turn thermostat to the extreme counterclockwise position.
5. Push disconnect switch into ON position.
6. Latch at bottom of heater assembly should be in up position.
7. Mount grille over tabs on fan deck and push down until grille is secure.
8. Insert screwdriver through bottom louver in grille and loosen screw while
holding bottom of grille against wall. This will allow latch to drop in place.
Tighten screw.

Installation of Back Box with Optional
Surface-Mounting Frame WHSM (See Figure 4)
1. Secure back box to wall with knockouts in upper right hand corner using
screws and anchors.
2. Hang the surface-mounting frame on the back box. Ensure that the back
edge of the surface-mounting frame is flush against the wall.
NOTE: If heater is located in a high traffic area, where it may be subjected to vandalism or abuse, take extreme care to see that the box is firmly
attached to the wall.
Fig. 5
3. Power Supply Wiring
NOTE: Wiring Compartment Volume - 119in3 (1950cm3).
a. Run a power supply cable into the area to the right of the mounting
frame. Arrangement of wiring to this point must be in accordance
with National and Local codes.Refer to specifications on page 2 for
proper wire size.

Operation
1. Rotate the thermostat fully clockwise. This should energize the heating
elements and cause warm air to flow from the hot air discharge at the
openings in the bottom of the grille.
2. After the operation check, rotate the thermostat to the desired position to
obtain room comfort.
NOTE: For best results, the heater should be left “ON”
constantly during the heating season because the thermostat, when properly
set, will maintain the desired temperature.

Cleaning & Maintenance
To maintain optimum performance and efficiency, heater should be cleaned
and checked periodically. It is recommended the heater be cleaned at least
annually. (more often if used in a dirty environment)

“knockout” from the top of the box and
proceed to step C.
b. Remove the “knockout” on the top side of the frame.
c. Remove disconnect switch bracket by loosening the two screws on
the right side.
d. Feed the power supply cable through the frame allowing 6" (152mm)
of lead to remain inside the back box (using cable clamp, connector,
or other suitable strain relief).
e. Secure the power supply cable to the back box (using cable clamp,
connector, or other suitable strain relief) allowing 6" (152mm) of lead
to remain inside the back box.
f. Connect supply wires to blue wires of disconnect switch using wiring
connectors (see wiring diagram, pg. 4).
g. Ground the back box by connecting the supply ground leadwire to
the green ground screw located in the inside top of the back box.
h. Secure disconnect switch bracket in place.
TO CLEAN HEATER:
1. Disconnect power to heater at main panel or breaker.
2. Remove thermostat knob (if provided) and remove front cover (grille)
as follows: (See figure 4)
–Insert screw driver through bottom louver and loosen one screw that
holds latch mechanism.
–Lift front cover upward and pull top outward to remove.
3. Push ON/OFF switch to OFF position.

TO RESET MANUAL RESET LIMIT:
Your heater is equipped with a manual reset safety thermal limit control
that will automatically turn the heater off to prevent a fire if the heater overheats. This control is located on the fan panel assembly between the element and fan blade and marked “reset”. The red reset button can be seen
through the front grille when the heater is installed. To reset, allow the
heater to cool, then push the red button that is visible through the hole in
the fan panel. The heater should immediately return to normal operation.
